Mental Toughness for the Fight of Your Life

This year two million Americans will hear the words “You have cancer” and their lives will never be the same. I heard those words twice in two years and was thrown into a race I never signed up for. I didn’t find a finish line, but instead a fresh start, a re-commitment to service and the next chapter in my story about finding hope in our darkest moments.

About Athlete, Author, & Speaker

Dr. Jeffrey Reynolds

A nonprofit executive who has dedicated his career to helping others and strengthening communities, Dr. Jeffrey L. Reynolds is an accomplished marathon runner and triathlete who completed the grueling 140.6-mile Ironman Florida race in 2021.


Just months after crossing that finish line, he discovered that his athletic endurance and mental toughness would become essential tools when facing two cancer diagnoses within two years -prostate cancer followed by Stage 3B colorectal cancer. Drawing from decades of helping others through their darkest moments, he navigated surgery, chemotherapy and radiation with the same grit and discipline that carried him across finish lines.

Today he combines lived experience as a survivor with nationally recognized leadership to advance power of purpose, health equity, and strength and resilience for patients everywhere. His journey offers a roadmap for life after prostate cancer and beyond.

Jeffrey’s Story
